Large area fireproof decorative panels are used as wall materials for indoor decoration. Aluminum alloy edge strips need to be installed at the joints and corners between the panels to enhance overall aesthetics and protect the edges of the panels from bumps. This project uses a total of 12000 meters of silver gray aluminum alloy edging, including three specifications: T-shaped flat seam strips, L-shaped male corner edging strips, and U-shaped female corner edging strips. The surface treatment is powder coating, presenting a matte silver gray color, which forms a coordinated layering with the light gray decorative panel. During the installation process, the edge strips are fixed by buckles or adhesives, resulting in high construction efficiency. After the completion of the project, the overall wall lines were neat and modern, which was highly recognized by the owner and design unit.
